Yeah the only thing I didn't like about mine was that the extractors didn't work as well as they might have and the cokes were full and 3/4 when I would have liked them to be more open so I could have put slugs though it.
This one can take slugs, but I've never fired any out of it; usually keep some magnum 00-buckshot on hand.
I used that stuff too. It's great for ripping cans apart. Friend of mine used some to take a goose.
